might be a little late, but you can check your items collected in the leaderboards on the game. and honestly, i would have thought the same, but i bet you're not even close, ha ha. ive had several play-thrus and im only close to 5k at this point.

This is probobaly be the last achievement you pop. It takes forever. I've played through several times and still haven't unlocked it. To make it a little easier, make sure you have +15% loot drop (which is the cap). This means that all enemies have a +15% chance to drop loot, or a +15% chance to drop twice as much loot on leaders and bosses.

this achievemment is not glitched if u play on your own it will pop up by the 3 or 4 player that u get to level 50 but when u play online u share everything its called round robin .i got this the start of my 4 player but i played alot online

This achievement is glitched, I got more than 7500 according to the leaderboards, and I still don't have this achievement. I got around the crappy gameplay and even crappier controllers and long ass death sequence, but these last 2 achievements, completing the 7 piece suit and this one are fucking bullshit.

If you play alot online, it counts how many were dropped, but if you are playing round robin they get split between you and the other character. So it says 7745 or more but you are actually lower because of the ones that YOU GOT.

I wish this game had more for in game stats. If you put an achievement out like this. The game should have some kind of trackers for you.
